Abstract :
In this paper, we present a performance comparison of different WiMAX base station (BS) scheduling algorithms: deficit round-robin (DRR) vs. proportional fair (PF) vs. weighted deficit round-robin (WDRR). Our simulations show that when the radio channel conditions are taken into account (in PF and WDRR schedulers), the improvements in throughput can be considerable.
